Robot base stand

A robot base stand comprising:

• a first support table configured to mount a robot thereon;
• the robot fixed to the first support table;
• a second support table configured to place thereon objects to be handled by the robot;
• and
• a relative distance adjusting mechanism that adjusts a relative distance between the first support table and the second support table wherein the relative distance adjusting mechanism is configured to permit selection of one distance from a plurality of relative distances preset in accordance with types of the robot, wherein each of the preset distances is marked by an indicia indicative of the type of robot to be mounted to the first support table, wherein the relative distance adjusting mechanism includes:
• a plurality of first connecting portions that is provided in the first support table, extends in the direction of relative distance adjustment between the first support table and the second support table, and is spaced from each other in the horizontal direction perpendicular to the direction of relative distance adjustment;
• a plurality of second connecting portions that is provided in the second support table, extends in the direction of relative distance adjustment, and is spaced from each other in the horizontal direction perpendicular to the direction of relative distance adjustment;
• and
• a plurality of fixing parts for fixing the first connecting portions and the second connecting portions to each other, wherein the plurality of first connecting portions has an arm-like shape projecting toward the second support table, is displaceable horizontally with respect to the second support table in the direction of the relative distance adjustment, and is fixed with respect to the second support table at a position that is determined by the selected distance.
